Speciiealion of Letters Patent.

To all 'u2/0m t may concern.'

Be it lrnoivn that We.y llnnsrcn M. lion- Enrs and lmit D. Romera citizens ot the United Statesj residing at Joseph, in the county of Buchanan and State of M' 1 have invented certain neuy and useiul lmprovements in Machines for Balringlastry Products, ot whichr the following is a specifi-V cation, reference being had therein to the companying drawing. y

This invention relates to `machines lor baking pastry produ.v s, such for example as ice cream cones which are non* commonly known and aims 'to provide an entirely -automatic machine for making such products wherein no handling the batter or dough is necessary until the products are coml pletely baked and have been ejected or dis charged `trom the machine. The construction shown connection with a machine 'tor maling such ice cream cones, but it is obH viouslv usable to ilfoiin other articlea the only changes then required being` a corresponding; cha. in the shape of the mold itsellt and the core therefor.

ln s improved machine the molds are the product automatically balred. The cores oi the molds are Withdrawn and the molds are then opened, whereupon certain eiectinr; devices positively 'torce the baked cones `out oit the molds and carry them to a cutting; device whereby any superfluous material iacut from them so to cause their being;1 discharged from the machine in pei te-ct form.

in additional object is to provide improved devices for evenly and thoroughly baking' sach pastry products and to this end the construction is such 'that the molds are inverted during part of their travel whereby mlied 'to all sides oit the mold at s. lee et the operation and therefore the products are more evenly baked.

in additional object is to provide improved d. eine devices 'tor the baked product., these devices comprising automatic means whereby the sections oi the mold are opened and certain ejeeting devices positively inserted after the cores are Withdrawn troni the molds. These ejectors are shaped more or less similarly to the cores themselves and serve to detach the halted products from the mold sections if that is necessaryand to force them positively out ,et the mold thus cutting device then automatically cuts the refuse batter so to perfect the siane ot Y A iJ the cone and discharges the baked cone from the machine. Also, an improved m" "i nism is provided for stripping the refuse batter from the cutting` mechanism and permittinn` its discharge out olf the machine.

An additional object is to provide an improved device :tor permitting the'escape oi: steam from the batter. The batter is7 et course?` somewhat moist when it is poured into the molds and as these are hot aconsids erable amount of steam is formed. This steam must be permitted to escape from the mold, but very shortly the amount of steam so escaping becomes less and then the steam escape may be largely shut oil. The machine oi this invention produces this result by permitting the cores to rest li ghtly in the molds duringv the iii-st part ot the baking operation and then to force them more tightly into the molds after the greater porA tion of' the steam has escaped.

ifi. further object is to provide improved means iior stopping the operation of the devices Which automatically lill or load the molds Without stopping the rest oi the machine. This construction is oit advantage when it is desired to start a. machine and to preheat the molds and also When it is desired to stop the machine, but to permit the coin- -pletion of baking of cones which then in process ot being baked in the machine.

A further object is to lock the molds in an erect condition at the discharging position. To this end the mold carrier is held against bodily movement, and the molds themselves are held against any movement et rotation.

in additional object is to provide tor making;` lighter or darker pastry elements by varying separately the supply of and air whereby more or less heat may be applied to the molds.

A machine as above described is shown completely in the drawings ioiininp` part ot this specification and in these f raivings. Figs. l to 6. inclusive, are somewhat ,freneral views; Figs. to 147 inclusive, show the cone discharging` mechanism and its diitfen ent features; Figs.. l5 and i6 shov.T means for inverting the molds whereby an. even
